"We began the political revolution in the 2016 campaign, and now it's time to move that revolution forward," Sanders said.

Sanders sent a campaign email announcing that he will once again seek the Democratic nomination, jumping into a crowded field of nearly a dozen candidates that will probably have to make room for many more.

"I’m running for president because, now more than ever, we need leadership that brings us together – not divides us up," he wrote in an email to supporters. "Women and men, black, white, Latino, Native American, Asian American, gay and straight, young and old, native born and immigrant. Now is the time for us to stand together."

In his announcement, Sanders called President Donald Trump "the most dangerous president in modern American history," as well as a "pathological liar, a fraud, a racist, a sexist, a xenophobe and someone who is undermining American democracy as he leads us in an authoritarian direction."

Sanders' 2016 surprise success

Sanders ran for the Democratic nomination in 2016, posing a vibrant – but ultimately unsuccessful – challenge to former Secretary of State Hillary Clinton.

Sanders' grassroots, anti-establishment campaign, which leaned heavily on small donors, sparked passion among his supporters – many of them young people engaging in electoral politics for the first time.

His strong showing surprised many in the political world and established Sanders as a national figure, giving him a prominent platform for his views as his decidedly left-leaning stand on issues gained influence within the party.

In his previous campaign, Sanders labeled himself a Democratic socialist, a platform seen as too radical by the Democratic Party establishment.

This time around, those same ideas – such as Medicare for all, a higher minimum wage, free college tuition – have been embraced by mainstream candidates seeking the Democratic nomination.

Sanders faces challenges in 2020

Sanders' 2016 success in many ways puts the senator in a more challenging position for his 2020 run.

Running as a little-known candidate with an unusual message from a tiny state, Sanders gained media attention almost as a novelty and initially escaped the kind of deep scrutiny top-line contenders typically face.

This time around, Sanders has one of the highest name recognitions among Democratic contenders, trailing only former Vice President Joe Biden, who is likely to announce whether he'll jump into the 2020 race in the coming days.

That high profile makes Sanders one of the candidates to beat, meaning he will probably be targeted by other Democratic hopefuls.

Sanders will continue to face questions about the allegations of sexual harassment and the treatment of female staff members and volunteers stemming from his 2016 campaign.

Then there's the question of age.

At 77, Sanders is the oldest among candidates who have announced, as well as those who are likely to enter the race.

Sanders will need to convince Democratic voters that an older white man is the right candidate in 2020 when the party is riding a wave fueled by a focus on diversity and the #MeToo movement.

Sanders sounds familiar notes

In his email Tuesday, Sanders offered a long list of issues that are likely to become familiar notes of his campaign speeches in the coming months.

Sanders targeted what for him are the usual suspects – "Wall Street, the health insurance companies, the drug companies, the fossil fuel industry, the military-industrial complex, the private-prison industry and the large multi-national corporations."

He hammered home the message of his fight against inequality and discrimination.

Sanders put out a call to his supporters.

"I am asking you today to join me as part of an unprecedented and historic grassroots campaign that will begin with at least a million people from across the country," he wrote. "They may have the money and power. We have the people. That is why we need one million Americans who will commit themselves to this campaign."

A campaign spokesperson said Sanders has no public campaign events planned for Tuesday.

Brothers and Sisters--

I am writing to let you know I have decided to run for president of the United States. I am asking you today to join me as part of an unprecedented and historic grassroots campaign that will begin with at least a million people from across the country.

Please join our campaign for president on day one and commit to doing what it takes to win this election.

Our campaign is not only about defeating Donald Trump, the most dangerous president in modern American history. It is not only about winning the Democratic nomination and the general election.

Our campaign is about transforming our country and creating a government based on the principles of economic, social, racial and environmental justice.

Our campaign is about taking on the powerful special interests that dominate our economic and political life. I'm talking about Wall Street, the health insurance companies, the drug companies, the fossil fuel industry, the military-industrial complex, the private-prison industry and the large multi-national corporations that exert such an enormous influence over our lives.

Our campaign is about redoubling our efforts to end racism, sexism, homophobia, religious bigotry and all forms of discrimination.

Our campaign is about creating a vibrant democracy with the highest voter turnout of any major country while we end voter suppression, Citizens United and outrageous levels of gerrymandering.

Our campaign is about creating a government and economy that works for the many, not just the few. We are the wealthiest nation in the history of the world. We should not have grotesque levels of wealth inequality in which three billionaires own more wealth than the bottom half of the country.

We should not have 30 million Americans without any health insurance, even more who are under-insured and a nation in which life expectancy is actually in decline.

We should not have an economy in which tens of millions of workers earn starvation wages and half of older workers have no savings as they face retirement.

We should not have the highest rate of childhood poverty of almost any major country on Earth and a dysfunctional childcare system which is unfair to both working parents and their children.

We should not have a regressive tax system in which large, profitable corporations like Amazon pay nothing in federal income taxes.

Make no mistake about it. The powerful special interests in this country have unbelievable power and they want to maintain the status quo. They have unlimited amounts of money to spend on campaigns and lobbying and have huge influence over the media and political parties.

The only way we will win this election and create a government and economy that works for all is with a grassroots movement – the likes of which has never been seen in American history.

They may have the money and power. We have the people. That is why we need one million Americans who will commit themselves to this campaign.

Stand with me as we fight to win the Democratic nomination and the general election. Add your name to join this campaign and say you are willing to do the hard work necessary to transform our country.

You know as well as I do that we are living in a pivotal and dangerous moment in American history. We are running against a president who is a pathological liar, a fraud, a racist, a sexist, a xenophobe and someone who is undermining American democracy as he leads us in an authoritarian direction.

I’m running for president because, now more than ever, we need leadership that brings us together – not divides us up. Women and men, black, white, Latino, Native American, Asian American, gay and straight, young and old, native born and immigrant. Now is the time for us to stand together.

I’m running for president because we need leadership that will fight for working families and the shrinking middle class, not just the 1 percent. We need a president who understands that we can create millions of good-paying jobs, rebuild our crumbling infrastructure and construct the affordable housing we desperately need.

I'm running for president because we need trade policies that reflect the interests of workers and not multi-national corporations. We need to raise the minimum wage to a living wage, provide pay equity for women and guarantee all workers paid family and medical leave.

I'm running for president because we need to understand that artificial intelligence and robotics must benefit the needs of workers, not just corporate America and those who own that technology.

I'm running for president because a great nation is judged not by how many billionaires and nuclear weapons it has, but by how it treats the most vulnerable – the elderly, the children, our veterans, the sick and the poor.

I’m running for president because we need to make policy decisions based on science, not politics. We need a president who understands that climate change is real, is an existential threat to our country and the entire planet, and that we can generate massive job creation by transforming our energy system away from fossil fuels to energy efficiency and sustainable energy.

I’m running for president because the time is long overdue for the United States to join every other major country on Earth and guarantee health care to all people as a right, not a privilege, through a Medicare-for-all program.

I’m running for president because we need to take on the outrageous level of greed of the pharmaceutical industry and lower prescription drug prices in this country.

I'm running for president because we need to have the best educated workforce in the world. It is totally counter-productive for our future that millions of Americans are carrying outrageous levels of student debt, while many others cannot afford the high cost of higher education. That is why we need to make public colleges and universities tuition free and lower student debt.

I’m running for president because we must defend a woman’s right to control her own body against massive political attacks taking place at the local state and federal level.

I'm running for president because we need real criminal justice reform. We need to invest in jobs and education for our kids, not more jails and incarceration. We need to end the destructive "war on drugs," eliminate private prisons and cash bail and bring about major police department reform.

I'm running for president because we need to end the demonization of undocumented immigrants in this country and move to comprehensive immigration reform. We need to provide immediate legal status for the young people eligible for the DACA program and develop a humane policy for those at the border who seek asylum.

I'm running for president because we must end the epidemic of gun violence in this country. We need to take on the NRA, expand background checks, end the gun show loophole and ban the sale and distribution of assault weapons.

I'm running for president because we need a foreign policy which focuses on democracy, human rights, diplomacy and world peace. The United States must lead the world in improving international cooperation in the fight against climate change, militarism, authoritarianism and global wealth inequality.

That is why we need at least a million people to join our campaign and help lead the movement that can accomplish these goals. Add your name to say we’re in this together.

Needless to say, there is a lot of frightening and bad news in this world. Now, let me give you some very good news.

Three years ago, during our 2016 campaign, when we brought forth our progressive agenda we were told that our ideas were "radical," and "extreme." We were told that Medicare for All, a $15 an hour minimum wage, free tuition at public colleges and universities, aggressively combating climate change, demanding that the wealthy start paying their fair share of taxes, were all of concepts that the American people would never accept.

Well, three years have come and gone. And, as result of millions of Americans standing up and fighting back, all of these policies and more are now supported by a majority of Americans.

Together, you and I and our 2016 campaign began the political revolution. Now, it is time to complete that revolution and implement the vision that we fought for.

So here is my question for you:

Will you stand with me as part of a million person grassroots movement which can not only win the Democratic primary, not only win the general election but most importantly help transform this country so that, finally, we have a government that works for all of us and not just the few? Add your name to say you will.

Together we can create a nation that leads the world in the struggle for peace and for economic, racial, social and environmental justice.

And together we can defeat Donald Trump and repair the damage he has done to our country.

Brothers and sisters, if we stand together, there is no limit to what we can accomplish.
